Premature ventricular contraction-induced dilated cardiomyopathy: a case report.

ABSTRACT:

Background

Premature ventricular complexes (PVCs) are ectopic heartbeats caused by early myocardial depolarizations, previously thought to be benign. Recent studies found high PVC burden above 24% can induce or contribute to cardiomyopathy and heart failure. We present a case of PVC-induced dilated cardiomyopathy (DCM).

Case summary

A 68-year-old woman was admitted with pneumonia after an overseas trip with a preceding viral respiratory tract infection. An initial chest X-ray was suggestive of cardiomegaly. A transthoracic echocardiogram (TTE) revealed DCM with global systolic dysfunction (left ventricular ejection fraction <30%) without valvular lesions. Biochemistry and coronary angiography were normal. Clinical deterioration occurred despite medical therapy. A 24-h Holter
